I have a girl that wants a pulled sugar rainbow on a baby shower cake. I was wondering what I need to do this, and how to get started. Thanks for the help.

I suggest you browse through the topics in this forum. The following is a starter topic is an equipment list, however there are a lot of other topics that have been started that should answer quite a few of your questions. One one of the pages as I was browsing through someone had posted a link to a video of working with pulled sugar.
